External storage device

Abstract

An external storage device includes a case, a storage unit, a communication interface, a main control chip, a touch pad, a touch pad controller, a voice controller and a speaker. The storage unit is mounted in the case. The communication interface is used to communicate with a computer. The main control chip is electrically connected to the communication interface and the storage unit. The touch pad is mounted on the case. The touch pad controller is electrically connected to the touch pad and the main control chip. The voice controller is electrically connected to the main control chip to generate a voice signal according to the operational state of the main control chip. The speaker is mounted on the case and electrically connected to the voice controller to output the voice signal.
